Got Arm Swing?
We have written many times about arm swing. Click here for some of our posts here on Tumblr.
Here we are again at the beach. Look at the beautiful difference in arm swing from side to side in the guy carrying the bag. Makes you want to tell him to use a backpack, eh?
Never mind what it does to his gait
- decreased arm swing on the carrying side
- increased step length on the left side
- increased thigh flexion of the left side
- increased body lean and head tilt to right side (Take a look at this paper)
think about the increased metabolic cost. Think about what this type of input (increased amplitude of movement unilaterally) is doing to your cortex!
keep your movements symmetrical, folks!
